Designed for longitudinal engine configurations, the series includes 4 forward gears and 1 reverse gear. The 4L60E is the electronically commanded evolution of the Turbo-Hydromatic 700R4, originally produced in 1982.\u003c\/p\u003e\r\n\u003cp\u003eMost of the 4l60\/65\/70Es you see in service today were originally manufactured in the Toledo, Ohio, plant for General Motors.\u003c\/p\u003e\r\n\u003cp\u003eThese transmissions cannot be differentiated from the outside by the average eye. The 4L65E shares the same exterior parts but has stronger internals, such as 5 pinion planets compared to 4 in the 4L60E. These also can carry several different input shafts depending on which version you have. The early 4L60Es had a 298mm input shaft for non-LS platforms while the later LS models utilized a 300mm one. The later 4L70E also utilized an input speed signal on the input shaft.\u003c\/p\u003e\r\n\u003cp\u003eAn updated 4L60E, the \u003cstrong\u003e4L65E\u003c\/strong\u003e (RPO M32), was phased in the 2001 model year when coupled behind the 6.0 Vortec. Five-pinion front and rear planetaries, along with an additional 3-4 clutch allowing 7 clutches in the input housing and induction-hardened input shaft assembly, were improved to withstand up to 380 ft-lbs (515 N-m) of torque.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 12pt;\"\u003eThe Category 1 Kit\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThis Category 1 SunCoast 4L60\/65\/70E kit has everything you need for a successful high performance rebuild.
